mini robots in our blood??!?!?!?!

This tiny .14 inch motor is the future of miniature robotics. Imagine tiny robots capable of navigating your blood stream and destroying virus's or clearing up clotted arteries that may lead to a stroke or heart attack...

(Caution Science Zone)
The motor to the right of the tip of a ball point pin works uses reverse piezoelectricity. Piezoelectricity is what allows barbecue grill lighters to work. The little red button that shoots a spark is made up of a little hammer that hits a small piece of crystal, usually quartz. This creates a very high voltage and sparks your grill burners.

Anyway by adding electricity, a small ceramic piston is made to oscillate, eventually turning the ball on the top. This of course can be used to propel the robot forward inside your blood stream.

The hope is to make these even smaller, attach them to robots and begin testing in model blood vessels. The research team of Monash University is confident they can produce even smaller motors, but as Brett Watson, a lead scientist on the team, said, "It's really hard to put the darn thing together."

How do you feel about motor driven robots in your blood stream? Is this a genius invention or a scientific catastrophe?

o yeah here's the original article and image source.
